Lag screws, especially through the plate, must be avoided whenever possible. Find articles by Juerg Sonderegger Karl R.
It is widely accepted to achieve bone healing with a dynamic and biological fixation where the perfusion of the bone is left intact and micromotion at the fracture gap is allowed. Lag screws and screws close to the fracture site reduce micromotion dramatically. Lag screws were used to obtain compression at the fracture site.
Abstract Plate osteosynthesis is one treatment option for the stabilization of long bones. Long plates and oblique screws at the plate ends increase fixation strength.
Grob Find articles by Karl R. This kind of osteosynthesis resulted not only in lack of callus formation but also in decreased bone perfusion.
Compression is not required. Bone healing was delayed in many cases and hardware failures were often the result. However, the number of screws does influence stiffness and stability.
Oblique screws at the plate ends increase the pullout strength. Two or three holes at the fracture site should be omitted.
Periosteum and muscle tissue had to be removed to obtain an anatomical reduction of all fragments. The indications for a dynamic plate osteosynthesis include distal tibial and femoral fractures, some midshaft fractures, and adolescent tibial and femoral fractures with not fully closed growth plates.
The surgeon performing a plate osteosynthesis has the possibility to influence fixation strength and micromotion at the fracture gap. Dynamic plate osteosynthesis can be achieved by applying some simple rules: Although many lower limb shaft fractures are managed successfully with intramedullary nails, there are some important advantages of open-reduction-and-plate fixation: When respecting these basic concepts, dynamic plate osteosynthesis is a safe procedure with a high healing and a low complication rate.Biological osteosynthesis differs from traditional open reduction and internal fixation in two main aspects: the invasiveness of the surgical approach and the function of the implants applied to stabilize the fracture.
[Biological osteosynthesis]. [Article in German] Biological fracture fixation means: conservation of bone perfusion, protection of the soft tissue envelope and reduction of systemic stress by strengthening the host-defense mechanism. For preoperative planning, the following points have to be considered: choice of fixation method, reduction.
MINIMALLY INVASIVE OSTEOSYNTHESIS IN NON-DIAPHYSEAL FRACTURES Kenneth A Johnson MVSc, PhD, FACVSc, DACVS, DECVS became the foundation of a new concept known as “biological osteosynthesis”.
Adoption of MINIMALLY INVASIVE OSTEOSYNTHESIS IN NON-DIAPHYSEAL FRACTURES. The discussed method of open fracture reduction with minimal surgical access, referred to as the " open but do not touch " technique (Aron et. Based on biological osteosynthesis (BO) in medi- cine,  we need only adjust the two fragment ends to the proper position without considering the local status.
Our previous studies indicate the. Plate osteosynthesis is one treatment option for the stabilization of long bones. It is widely accepted to achieve bone healing with a dynamic and biological fixation where the perfusion of the bone is left intact and micromotion at the fracture gap is allowed.Download
